FULL DOWNLOAD SPEED BUT SLOW DOWNLOAD SPEED

Hi,

what is your hardware? If it is a PC based unit have you disabled speedstep in the bios?

The proof is if you try to run your speed test on a number of devices concurrently.

i tested also one device to connect at a moment but same speed issue.

Hi,

are all your XGS on the same XG software version?

Ian

yes same version

Please check the wan interface is set to either autonegotiate or full 1gbs connection.

the problem is this when i SPEEDTEST THE SOPHOS I GET THE FULL UPLOAD AND DOWNLOAD,

But when a device is connected to the sophos the speed got a full upload but slow download it stuck at 11 mbps

QoS setup somewhere?

QOS? its all default

AUTO NEGOTIATE

Hi,

there is always the possibility you have a faulty unit? I suggest you create a support case.

Check Traffic shaping settings, under System Services.

here disable Enforce Guaranteed Bandwidth, if enabled and keep the available bandwidth to highest 2560000 KB/s

I have been facing this speed/bandwidth issue during Video calls, made above settings and in every firewall rule (LAN-WAN) in traffic shaping / QoS selected none, no speed complaints anymore.

Also, just for information, in Sophos if you are doing Traffic Shaping the bandwidth is calculated in Kilo-Bytes/s. Had a good run with this too.
